NASA’s “Lucy” will take a 40,000-mile detour to visit this asteroid
NASA has added a tenth asteroid flyby to the record-breaking Lucy mission so that it can test a new asteroid-tracking system.
This near-Earth asteroid is 4.2 billion years old and nearly indestructible
By analyzing just three dust particles, researchers learned that the rubble pile asteroid Itokawa is 4.2 billion years old and hard to kill.
Ancient killer asteroid created a megatsunami on Mars
3.4 billion years ago, an asteroid impact created a megatsunami on Mars that extended for 1500 kilometers. Here's the fascinating story.
Space ads could earn $2 million a day, say Russian researchers
Space advertising could generate a profit, even though space ads would cost $65 million each, according to Russian researchers’ calculations.
NASA’s mission proves it can redirect an asteroid — and potentially save Earth
NASA has confirmed that its DART spacecraft altered the orbit of the Dimorphos asteroid — a huge win for planetary defense efforts.
Webb, Hubble capture spacecraft slamming into asteroid
DART collision images captured by NASA's Hubble and James Webb space telescopes show what happens when a spacecraft slams into an asteroid.
NASA’s DART spacecraft is about to smash into an asteroid
The DART spacecraft is now close enough to image the asteroid system it plans to slam into as part of NASA’s planetary defense efforts.
NASA was “completely wrong” about the asteroid Bennu
It wasn’t until landing on the asteroid Bennu that NASA learned its surface was more like a plastic ball pit than the relatively solid moon.
The cosmos can kill us in many ways. But the James Webb Space Telescope can help save us
Asteroid strikes, supernova explosions, and gamma-ray bursts are just a few of the ways the cosmos can kill us.
What happens if the Solar System’s largest comet collides with Earth?
The asteroid that caused the last mass extinction 65 million years ago was only 5 kilometers across — tiny compared to this one.
We have a new way to hunt for potentially hazardous asteroids
To help protect Earth from potentially hazardous asteroids, astronomers developed an algorithm to look for them in existing datasets.
An asteroid could wipe out an entire city – here’s NASA’s plan to prevent catastrophe
Cosmic bodies, like asteroids and comets, are constantly zooming through space and often crash into our planet.
This near-Earth asteroid may be a chunk knocked off of the moon
A near-Earth asteroid discovered in 2016 may have once been part of the moon — making it unlike any space rock we’ve ever discovered.
Nuking an asteroid heading to Earth really could protect us
Blowing up an asteroid heading to Earth with a nuclear bomb could save the planet, according to new planetary defense simulations.
Astronomers discover solar system’s fastest-orbiting asteroid
Astronomers have discovered an asteroid that orbits the sun in just 113 days, making it the fastest-orbiting asteroid in our solar system.
Can Japan’s asteroid samples show us how life began?
JAXA’s Hayabusa2 has successfully returned asteroid samples to Earth. Its next mission? Gather information that could help prevent an asteroid impact.
Why NASA just landed a spacecraft on the asteroid Bennu
NASA has collected samples from the asteroid Bennu that could yield insights into everything from the origin of life to avoiding an asteroid impact on Earth.
MIT unveils simulation to help stop an asteroid impact
MIT has developed a simulation to determine the most appropriate way to stop an asteroid impact if one of the space rocks is headed toward the Earth.
